Greetings!  The issue here is that the preferred method of using bfd
is to absorb the library statically into libgcl.a, and there seems to
be no autoconf macros which can discern whether the static lib
available requires the libz or not.  Maybe a version check.  

This method is preferred because upstream binutils does not maintain
reliable soname versioning for use by external programs (they
explicitly say so), so dynamic linking can fail at runtime without
failing at link time.  Furthermore, the static lib allows image
production both via compiler::link and si::save-system without
recourse to source files under o/ for recompilation.

Speaking of which we probably need to update the local binutils tree
and backport Aurelien's macosx support for
bfd_get_relocated_section_contents. 

Take care,
